HERBAL MONOGRAPHS ST. JOHN'S WORT/723Wounds, bruising and swelling: The herb is applied topically
and locally for treatment. The activity of the topical
preparations is based on the hyperforin content, which is
highly variable depending on the method of oil preparation.
The preparation may be stable for a few weeks up to 6
months. (Maisenbacher & Kovar, 1992)
Homeopathic Dosage: The daily dosage for homeopathic
indications is 5 drops, 1 tablet or 10 globules every 30 to 60
minutes for acute therapy, and 1 to 3 times daily for chronic
use. Parenterally, 1 to 2 ml subcutaneously administered
three times daily for acute therapy and once daily for chronic
therapy. The ointment is applied 1 to 2 times daily for acute
and chronic use (HAB1).
Storage: Store at room temperature, away from heat,
moisture and direct light. Hyperici oleum has a limited shelf
life. One study showed that a sample containing 62
milligrams of hyperforin (the active ingredient in the oil)
contained no hypericin in 14 days. If sunlight is not used to
prepare the oil, then the breakdown is slower, but still less
than 30 days. Various oil preparation methods have been
described, including one with eutanol G, which showed
stability for 6 months. Researchers evaluated^ 6 commercial
samples of oil of Hypericum containing 2.2 to 20.8
milligrams/deciliter. All hyperforin was gone by the end of
five weeks (Maisenbacher, 1992).
